SIRUI Ultra Slim S-Pro Nano MC Circular Polarising Filter - stops reflections from water and glass surfaces The SIRUI Ultra Slim S-Pro Nano MC Circular Polarising Filter increases the colour saturation of the image, meaning whiter clouds and a bluer sky, for example. The filter also reduces reflections from non-metallic surfaces (water or glass). Thanks to its high quality, the SIRUI Polarising Filter achieves a polarisation rate of nearly 100%.
